Estes Composite Motors - Coming Soon!

[GregGleason]

Getting back to the topic of the OP, I went to the Estes site yesterday to search for anything regarding the composite motors, but "no joy".

However, today I ran across Estes Technical Note 2, which has a section titled "A Method For Calculating Chamber Pressures of Estes Model Rocket Engines".

Unfortunately that PDF file is a tad screwed up.

Yep, it's kind of "cut-n-paste" in places. Hopefully, it still good enough to be useful.

Problem is, the bottom fourth of each page is completely missing.

I'll go bug'em about it on Facebook.

[later] Done. We'll see if JumpJet is right about them paying attention to Facebook!

[a week later] Yep, they pay attention to Facebook. The file is now repaired!

I've seen dates from October to December.

 

[GregGleason]

The card on the table says "Fall 2011".

I don't know if they will make their debut in distribution chains first or at a national launch somewhere. I think that NARAM would be a great place, but that looks like it would be way too early to pull off.

I have my doubts with Estes. They have produced a whole lot of vapor ware in the past. I hope their new owners are different.

I hear you on your doubts. But I am optimistic, because of the new management, that these motors have a high likelihood of coming to market.

This is from an Estes FB post from May 9 (to a different Andrew!):

Andrew, Currently we have 4 rockets being developed in the Pro Series II line. We are also working on Sonic Igniters for the Pro Series II rockets and currently nine composite engines, being E, F and G power. Our projected release date is prior to December 1 at this time. Thanks for asking!

If the December release date holds, I think I know what I want in my stocking for Christmas.

I've had my doubts with them in the past, but things are looking up. They've released a bunch of new kits and re-released several classics, though some aren't exact copies. They've certified the A8-0 and A10-0T again. John Boren is active on the rocket forums.

Since the new composite motors look like they are re-badged from Aerotech, it shouldn't be a tough thing to accomplish. I would hope that they wouldn't promote the motors if the contract with Aerotech hasn't already been signed, sealed, and delivered.

Gary Rosenfield confirmed elsewhere that Aerotech is supplying the motors for Estes.

Yup. Which is stated in the sixth post of the original thread on this subject on YORF.
